The spectral-luminescent characteristics of mesoderivatives of pheophytin and its analogs were investigated in binar mixtures of solvents (ethanol--water; dioxane--water). The mesoderivatives were shown not to form stable longwave selfassociates. Under similar conditions the pheophytin mesoderivatives were inclined to the formation of stable mixed associates with pigments, containing vinyl groups and free keto groups in position 9. In mixed pigment associates the intracomplex excitation energy transfer discovered had an efficiency essentially lower than in mixed associates of chlorophyll and its analogs.
研究了脱镁叶绿素及其类似物的中衍生物在二元混合溶剂（乙醇 - 水；二氧六环 - 水）中的光谱发光特性。结果表明，中衍生物不会形成稳定的长波自缔合物。在相似条件下，脱镁叶绿素中衍生物倾向于与在9位含有乙烯基和游离酮基的色素形成稳定的混合缔合物。在混合色素缔合物中发现的复合体内激发能转移效率实质上低于叶绿素及其类似物的混合缔合物。
